Pros: most articulate sub $100.00 bass I ever heard, buttery smooth mids, beautifully airy with WC clarity

Cons: stock tips, fit might be a bit negligible to some, smoothed out treble

I've spent the past week auditioning these new VSD1S by VSonic. Before this I was listening extensively to my dual dynamics JVC FXT90's and my dual armature UE 700. For a single dynamic driver that is priced below $50.00, you get something tuned to compete with above $100.00 IEM's. Within a few hours, I realized that my VSD1S sounded as accurate and sonically equal to my dual FXT90! Though the FXT90's revealed more details in your music, and had greater instrument separation and timbre ability, the sheer SMOOTHNESS of the mids and the bass simply stood equal to the FXT90's, due to the aggressive mid nature of the 90's, and the lack of smoothness in the sound of those dual carbon drivers. The bass is more articulate and rounded in the Vsonics as well. Though they don't dig as deep or punch as hard, the ability of the bass to produce clear and thoughful notes and provide blinding speed on the low end is simply too impressive to ignore. The mids are exceptionally smooth and clear, with just the slightest bit of coloration to give it that snappy fun sound without losing too much transparency. These things are almost as transparent as the RE-ZERO's. Not quite, but they definitely are a close second, while trouncing the FXT90's. Transparency and soundstage is also greater than the UE 700. No small feat since the 700's are a dual TWFK armature driver IEM. the high end is where you will be left for want if coming from the armature crowd or the JVC crowd. The sparkly, strong treble presence of those types of IEM's is not present here. These are laid back highs. I'd say more subdued and eloquent highs. The cymbals and crashes and clicks and brushes come out clear and have presence, but not the extension or strength you might find in a BA driver. This is well balanced, and beautiful. Nothing offensive at all with the sound signature. You could say the sound signature is ELEGANT. This is the beautiful woman walking across the room, that everyone takes notice of, who is powerful yet understated, despite more overt and stunning women in the room. These are my budget champions. I don't believe a better sounding budget IEM exists. IMHO. Why? because these can handle ANY genre of music to sonic perfection, and do it at a price reserved for $100-200 IEM's with multiple drivers. I've got the Fidelio S2 on order, as well as the T-PEOS H-100, and after hearing the VSD1S, i'm not so excited about either anymore, and I think there won;t be much improvement over these budget Kings. 




Pros: Great sound for the price. Unique and special tuning. Fun and very musical.

Cons: Stock eartips. Need to be worn upwards for best fit and comfort but channels are swapped.






Driver: 11mm Driver units 
Rated Impedance: 32 Ohm
Sensitivity: 110 dB
Frequency Response: 10-22000 Hz
Distortion: <2% 
Channel Balance: < 3 dB
Rated Power: 10 mW
Maximum Input power: 50 mW
Plug: 3.5mm dual channel plug
Cable: 1.30 TPU Cable, 4 X 20 core high purity silver plated wires +/- 3%

Build & Design:

The overall build quality is quite good. The oval-shaped earpieces are made of plastic, but feel sturdy enough. The silver colored cable, while a bit thin, is soft and not very tangle-prone. It's ended in an L-plug.
The special feature is the adjustable nozzle which is a huge advantage to achieve a perfect fit.






3 pairs of single-flange tips (S/M/L)
1 pair of bi-flange tips
4 pairs of foam tips (on 4 different colors)
1 pair of earguides
A shirt clip
And a soft carry bag
Unfortunately the nice array of hybrid-style eartips is not included anymore.




Comfort, Fit & Isolation:

When worn with the cable up and around the ears, the VSD1 are very comfortable. The downside is that this way the channels are swapped. I tried to wear them cable down, but it was impossible for me. So, for an over-the-ear design the fit is pretty easy, mostly because of the adjusting nozzle. 
Isolation is decent. Nothing great, but about average (or slightly above). Enough for daily use.
As for the eartips, the silicone ones are a bit stiff so I ended using some aftermarket tips with a very similar design and texture as the stock ones to keep the same sound.


These new VSD1-S, together with the VSD1, are supposed to be the first (and lower) models from VSONIC new series, the VSD. The company itself promoted both VSD1 being an 80% from the current flagships, the GR07 models. While I can't confirm that, personally I don’t think it really matters, as these ones are already too good by themselves. As for the VSD1-S model they have a unique and exquisite sound, a special coloration.
Starting from the low-end. They are by no means a bassy earphone, but the Bass is north of neutral for sure. Something in the middle way, close to having the "perfect" quantity for most genres, although many people might still find them lacking. Quality-wise, they're great. Something not easily found in the sub $50 category. The lows have the typical VSONIC presentation, very nice texture with enough punch, kick and rumble. Still, Sub-bass doesn’t extend very deep.
Highs, in their own way, share a similar description as the lows. Upper highs feel smoothen down a bit, which is good, as they're no annoying piercing peaks, at least when listening at low-to-moderate volumes (and with the VSD1-S there's no need for rising to a higher level, as they very easy to drive). While previous VSONIC models were reported to have a tendency of being sibilance prone, it is not the case with these (again, unless played at higher volume). The details are quite surprising, while they may not compete against something on the $100+ range, they match, and put on shame, many IEMs on the $50-80 range.
As for the low-highs they must be described together with the midrange, specially the upper-mids, because here's where the VSD1-S strength lies.
There's a very obvious separation between low-mids and upper-mids. The midrange is slightly forward, but cannot be called a mid-centered signature due to the well present highs and lows. Lower-mids sound clear and detailed, never recessed, but they will sound drier and less emphasized compared to the upper-mids. 
Upper mids and lowest highs not only sound forward and thick taking the leading role, but also have a special texture and sweetness. The best way to describe them is "Fun and Very Musical". Female/Upper vocals are the main attraction here, and that's actually how VSONIC described the VSD1-S tuning. They may sound a bit aggressive and shouty.
The coloration and unique presentation is similar to the famous Fischer Audio Eterna. Of course each on its own frequency, the Eterna with their special fun low-end, and the VSD1-S on the lower-highs/upper-mids (and needless to say that the quality is way much better). It's very catchy and full of energy. 
On the other hand soundstage is nothing special. In fact it's a kinda narrow (not unlike other mid-centered earphones).
Do I really need to say these new VSONIC's have an outstanding value? 
They're already comfortable and sound too good for the price. But the main reason to recommend them is for their special sound. A Must not only for every VSONIC fan, but also for anyone that truly wants to enjoy his/her music.

Introducing the VSD1S, the companion to the VSD1. it is designed to be the baby brother of the famed GR07 series. While it is priced at almost 1/3 of the price, Vsonic claims that it retains almost 80% of the sound making it one of the bang for the buck earphone in the series. VSD1S has a larger soundstage and has a slightly less bass response than the VSD1 making it perfect for classical and jazz music.
